Good on ya, Mark. cool

As a person that has used and repaired a lot of welders in the past, I'd be interested to hear what the response of the ESS is.

I had a look through all of the Reg's, ECP's and Standards I have here and only found a reference to welders in as far as maximum demand calcs are concerned.
